A kind of distance increasing unit generator, including the power input shaft being mounted on the rotor；Power input shaft starts with distance increasing unit
Between the flywheel of machine, it is connected with the torque limiter for overload protection.When engine power output is unstable, pass through torque
Limiter, so that the power input torque of generator is more stable, to improve the runnability and service life of generator.
Preferably, power input shaft is splined shaft, and power input shaft is connect by spline with torque limiter.Flower
Bond structure stable connection, and it is easy for assemble or unload, it is convenient for safeguarding.
It preferably, further include shell, the rotor and stator of generator are assemblied on shell, and shell is fixedly mounted on
On type range extender engine cylinder body.The rotor of generator is become one with stator by shell, individually assembly is avoided and generates
The problem of the difference of operation stability caused by error.
Preferably, it is provided with ring flange on shell, mounting hole is provided on ring flange, is set in type range extender engine
It is equipped with the screw hole to match with mounting hole, bolt, which passes through mounting hole and screw hole assembly, makes shell be mounted on type range extender engine cylinder body
On.Flange plate structure stable connection, and it is easy for assemble or unload, it is convenient for safeguarding.
Preferably, further include oil cooler, oil cooler is mounted on shell, oil cooler by insulating oil to rotor and
Stator is cooled down.Heat is generated in generator operation, and operation stability and equipment life are impacted, it is cold by oil
Device cools down rotor and stator, to improve equipment operation stability and service life.
Preferably, water cooler is installed on oil cooler, water cooler by outer loop condensed water to insulating oil into
Row cooling.Integrated water cooler, it is cooling to insulating oil by outer loop water, it further increases equipment operation stability and uses the longevity
Life.
In conclusion by adopting the above-described technical solution, compared with the prior art, the beneficial effects of the utility model
It is:
1, when working, flywheel and generator do not use hardwired mode by bolt, use flywheel by torque
Torque limiter is passed to, then by way of connecting with generator power input shaft spline transmitting torque by torque limiter.
To improve generator operation stability, and improve the service life of generator.
2, when assembling, generator is directly loaded on engine as a whole, avoids the occurrence of rotor and stator individually fills
There is the problem of turning with error and generator performance in timing.
3, this distance increasing unit generator is integrated with oil cooler, can be cooled down by insulating oil to rotor and stator, then by outer
Portion's condensed water cools down insulating oil.To improve generator runnability, and improve service life.
